Star rating is one of the most common international rating methods, and is most commonly used to rate the quality of hotels and restaurants, as well as many other goods and services. In addition, the concept of star rating has also been extended to the spoken word and literature, becoming a descriptive term to express grade.

The number and color of stars indicate the grade of tourist hotels. There are five levels of stars, namely, one-star, two-star, three-star, four-star, five-star, and the higher the star, the higher the grade of the tourist hotel. Four-star hotels for the higher grade.
